A hard fork on the Nakamoto Testnet is expected the week of September 23rd. Primary Testnet, following a successful fork of Nakamoto Testnet the week before, will occur the week of September 30th. The Nakamoto Testnet hard fork must be smooth and not surface additional bugs to proceed to the hard fork of the Primary Testnet. Again, any unexpected issues on these testnets could warrant selecting a later hard fork block.
The most helpful thing you can do is support testnet by using it, especially Signers!
